旁分泌细胞(paracrine cell) 内分泌细胞分泌的激素进入组织液,弥散至邻近的靶细胞,调节其机能,此方式称旁分泌,以区别于远距分泌——激素经血循环运送至远处、广泛区域的靶细胞。从旁分泌发挥其局部调节作用的内分泌细胞称旁分泌细胞,如散布于胃肠粘膜上皮的内分泌细胞、胰岛D细胞、分泌前列腺素的细胞等。旁分泌细胞分泌的激素经组织液弥散至邻近的靶细胞,起局部调节作用,称为局部激素(local hormone)。
结论肾素瘤是一种内分泌肿瘤,一般认为来源于肾小球球旁细胞。
Conclusions The tumor is a kind of endocrine tumor and is considered to be juxtaglomerular cell origin.
中药可能通过自分泌或旁分泌增加滋养细胞HB - EGF表达,增强滋养细胞的增殖及侵入和对缺氧的耐受。
Chinese Herbs may enhance expression of HB-EGF on trophoblast through autocrine and paracrine role, and may enhance proliferation, invasion and tolerance anoxia of trophoblast.
细胞可能同时具备内分泌、旁分泌和外分泌方式。
G cells may possess endocrine, paracrine and exocrine functions simultaneously.
Here, what's different between autocrine and paracrine is that there's some distance between the cell that produces the signal and the cell that receives the signal, but it's not too great a distance because the blood system doesn't have to be involved.
自分泌和旁分泌的区别在于,旁分泌中,产生信号的细胞和接收信号的细胞,之间存在着一定的距离,但这个距离并不远,因为血液系统并不参与
